Trigger Finger: Why It Happens and How We Treat It

Trigger finger is a common hand condition that causes your finger to lock or catch in a bent position—often due to tendon inflammation. Dr. Todd Pitts explains why it happens, how we treat it with conservative care or a minor surgical procedure, and what recovery looks like.

Symptoms of Trigger Finger:

Finger stiffness—especially in the morning
A popping or clicking sensation when moving the finger
Tenderness or a bump (nodule) at the base of the finger
Pain when bending or straightening the finger
Locking or catching in a bent position

Trigger finger (also called stenosing tenosynovitis) happens when the tendon in your finger becomes inflamed and can no longer glide smoothly through its sheath (a tunnel-like structure that keeps the tendon aligned with the bone). When this happens, the finger may get stuck in a bent position and suddenly pop straight—like a trigger being pulled and released.
It’s most common in people who perform repetitive gripping actions, but it can affect anyone.
- Non-Surgical Options:
  - Activity modification: Avoid repetitive grip-intensive movements
  - Bracing: Keep the finger straight to rest the tendon
  - Anti-inflammatory medications: Reduce swelling
  - Steroid injections: Targeted relief at the problem site
Trigger Finger Release Surgery:
- If symptoms persist or locking becomes painful and frequent, a quick outpatient procedure can relieve the tendon.
  - A small incision is made at the base of the affected finger
  - The opening of the tendon sheath is gently released
  - This eliminates the catching point and restores smooth movement
- Surgery time: ~10 minutes
- Immediate motion encouraged to prevent stiffness
- Mild soreness and stiffness for a few weeks
- Most patients regain full use of their hand and experience no more locking
Our goal is to help you return to full hand function without restrictions or pain.
